Some brackets would help.

I do not know what your actual question is :/

What situation?

(x-h)^2=4a(y-k)

(h,k ) is the vertex and a is the focal length.

I am glad that you father is fairly sensible about guns Dragonlance.  :)

Yes Joker, I expect you are right.

I am from Australia, we are saner down here :)

What is the exp for?

exp(​((x-​4)^​2+​(y-​4)^​2)^​2/​1000)

+​exp(​((x+​4)^​2+​(y+​4)^​2)^​2/​1000)

+​0.1*​exp(​((x+​4)^​(2*​y)+​4)^​2)^​2

+​0.1*​exp(​((x-​4)^​2+​(y-​4)^​2)^​2)

I am sorry, I do not know.

It seems to me that the repair guy is working on those machines about 12 out of each 22 hours.  If the machines are running 24 hour a day that is more than a full time job.  

The tech should just be a full time employee.  I expect it would be cheaper for the company that way and you would not have to work out this question SO it really would be better for everyone :)

I could suggest to you parents that they keep the alcohol with their guns so that you would be better protected but since I assume you are from the USA I expect that would be the least safe place :/

Some teachers have no sense of houmour do they Dragonlance :)

Let me guess where you are from, maybe Iowa or South Dakota?

|2-|x-3||=1 

2-|x-3|=1                             OR         2-|x-3|=-1

-|x-3|=-1                              OR       -|x-3|=-3

|x-3|=1                                 OR       |x-3|=3

x-3=1          OR    x-3=-1        OR       x-3=3    OR     x-3=-3

x=4             OR    x=2            OR       x=6    OR     x=0

Well if I do not see you one the forum in the next day of two I will assume that you are unconscious.

I would worry but I know your little sister will make sure you are well looked after :)
